“What a wonderful thing the skin is! It is the largest and most important integument of the whole human organism!
What millions of pores it contains! The minutest aperture might absorb the deadliest poison.
Once in contact with the surface of the body, whether the particle be held in a miasma, or dissolved in the water of ablution, the pore, like a fatal canal, conveys it into the system, whence its eradication may be impossible, and where it may generate untold mischief.”
— “Skin, Baths, Bathing, and Soap,” Francis Pears for Pears Soap, 1859
